In this page area of sector worksheet we are going to see 10 problems in the form of quiz.

Generally we are having two formulas to find area of any sector. We can use any either formula depending on the details given in the question.

**Area of the sector = (θ/360) x Π r
² square units **

**(or) Area of the sector = (1/2) x l r square units **

θ - central angle formed by the sector

L - length of arc

r - radius of the sector

We can use the first formula if the central angle(θ) formed by the sector and radius given. If the length of arc(L) is given we have to use the second formula only.

**Question 1 :**

**Find the **** area of sector whose perimeter is 78 cm and central angle is 45**°

**Question 2 :**

**Find the **** area of sector whose perimeter is 64 cm and central angle is 60**°

**Question 3 :**

**Find the **** area of sector whose perimeter is 92 cm and central angle is 36**°

**Question 4 :**

**Find the ****area of sector **whose perimeter is 43 cm and radius is 10.5 cm

**Question 5 :**

**Find the ****area of sector **whose perimeter is 86 cm and radius is 21 cm

**Question 6 :**

**Find the ****area of sector **whose perimeter is 56 cm and radius is 10 cm

**Question 7 :**

**Find the ****area of sector **whose perimeter is 64 cm and radius is 14 cm

**Question 8 :**

**Find the ****area of sector **whose perimeter is 45 cm and radius is 10 cm

**Question 9 :**

**Find the ****area of sector **whose perimeter is 147 cm and radius is 35 cm

**Question 10 :**

**Find the ****area of sector **whose length of arc is 21 cm and radius is 66 cm
